You can register for free as an advertiser or publisher directly from our website here: https://app.getfluence.com/en-GB/register
You'll need to specify whether you're an advertiser, looking for media on which to communicate, or a publisher, wishing to add your media to our catalog to receive orders. You'll be asked a few additional questions, but it doesn't take long!
Once you've registered, you'll have access to our marketplace, and can start exploring. All this is, of course, completely free!
